In view of the common drawbacks of superhydrophobic materials used for oil/water separation， such as unenvironmental raw materials，non-degradability and poor coating durability，etc. ，a simple and convenient impregnation method was adopted to prepare an environmental-friendly， excellent superhydrophobic material. Firstly， polymethyl methacrylate-co-glycidyl methacrylate P（MMA-r-GMA） polymer microsphere was fixed on the surface of cotton fabric using waterborne polyurethane （WPU）to construct micro-nano rough structure. Secondly，through a hydrolysis-condensation reaction，non-toxic hexadecyltrimethoxysilane（HDTMS）and methyltriethoxysilane（MTES）were anchored on the surface of thecotton fabric to prepare a superhydrophobic cotton fabric. The results show that the contact angle of the modified cotton fabric is up to 157. 3（o ）and the rolling angle is 5（o ）. At the same time，it has good solvent resistance，and the contact angle hardly changes after being immersed in an acid-base solution for 3 h. The oil-water separation efficiency can reach up to 97. 8%，even after 10 cycles of separation，the oil-water separation efficiency is still above 95%. It can be seen that the super-hydrophobic fabric prepared by this research has excellent oil-water separation efficiency and excellent stability，and can be used in the field of sustainable and environmentally-friendly oil-water separation.

Heavy metal ions have caused serious harm to the ecological environment and human health. It is urgent to treat heavy metal ions in water. In this paper，a co-precipitation method was used to prepare ethyl cellulose magnetic composite material（EC/Fe3O4）by using ethyl cellulose as a template to compound Fe3O4 nanoparticles with ethyl cellulose. The influence of the adsorption dosage，pH value of the solution， adsorption time and other factors on the adsorption process of Cu（II）in the solution was explored. The results show that EC/Fe3O4 exhibits good adsorption rate and adsorption performance. The adsorption equilibrium can be reached within 4 min. Under the adsorption conditions of Cu（II）concentration of 20 mg/L，solution pH of 7，and adsorption time of 160 min，the unit adsorption qe of EC/Fe3O4 is 76. 98 mg/g，and the maximum removal rate is 94. 68%. After 8 adsorption cycles，the unit adsorption capacity is 62. 21 mg/g. [ABSTRACT FROM AUTHOR]
